Hi Olivier,
We have added some improvements in Wi-Fi behavior in the v2.23.4 dev release. It’d be nice if you’ll be able to test it to check if it helps to eliminate the issue with accessing the device completely.
I’d like to point out that dev versions are mostly used for testing purposes and not intended for use for real field projects. Please note, once you update to the dev version, returning to the stable release will require the reflashing of the unit.
This fix will make it into the stable branch in one of the next updates, so you can wait until we push the stable to check if it resolves the issue.
